NBM Bus Converter NBM2317S60E1560T0R Non-Isolated, Fixed Ratio DC-DC Converter Features & Benefits Product Ratings (Step-Down Operation) Maximum continuous output power: 800W V = 54V (40 60V) I = up to 60A HI LO Up to 1kW, 2ms peak power capability V = 13.5V (10 15V) LO K = 1/4 Rated output current (step-down operation): (no load ) 60A continuous 100A transient, up to 2ms Product Description Rated output current (step-up operation): The NBM2317S60E1560T0R is a high-efficiency Non-Isolated Bus Converter operating from a 40 to 60V high-side voltage bus to 15A continuous DC deliver a ratiometric low-side voltage from 10 to 15V . 25A transient, up to 2ms DC 3 The NBM2317S60E1560T0R offers low noise, fast transient Up to 4.5kW/in power density response, and industry-leading efficiency and power density. In 97.9% peak efficiency addition, it provides an AC impedance beyond the bandwidth of most downstream regulators, allowing input capacitance normally Parallel operation for multi-kW arrays located at the input of a PoL regulator to be located at the high OV, OC, UV, short circuit and thermal protection side of the NBM. With a high-side to low-side K factor of 1/4, that capacitance value can be reduced by a factor of 16x, resulting in NBM2317 SM-ChiP package savings of board area, material and total system cost. 0.899 x 0.683 x 0.292in Leveraging the thermal and density benefits of Vicor SM -ChiP 22.83 x 17.34 x 7.42mm packaging technology, the NBM offers flexible thermal management options with very low top- and bottom-side thermal Thermally-adept SM-ChiP impedances. Thermally-adept SM-ChiP-based power components Bidirectional start up and steady-state operation enable customers to achieve low-cost power system solutions with previously unattainable system size, weight and efficiency Simple implementation, no external components required attributes quickly and predictably. Built-in hot-swap capabilities and inrush current limiting The NBM non-isolated topology allows bidirectional start up and steady-state operation and provides bidirectional protections.
